In 1796, Louis Philippe, Duke of Orleans, and future king of the France (1830-1848), agreed to an American exile on the condition that his imprisoned brothers would be released by the French Directory to join him. Guided in part by red lines drawn on a map by George Washington, Philippe and his brothers set out on a four-month, two-thousand mile journey into the American interior. When they returned to the frontier of western Pennsylvania, they met with General John Neville and Hugh Henry Brackenridge in Pittsburgh, stayed with Seneca Indians on the shore of Lake Erie, and later floated down the Susquehanna River, stopping briefly at the Pennsylvania colony of French Émigrés at Azilum.
